As Gorf pointed out, the only thing that matters is the HEPA. Most that are cheap are damaged, or that delivery will be 500 bucks so they don't wreck it?
I could be off base about delivery but I've heard of special shipments. If you can find cheap parts that are up to specs, DO IT!
But why? Are you working in a SAB for 8 hours a day? Are you working with bags that are too tall? Are you at a critical contamination point and a need a fix now because you're in production?
Sorry to rant at ya the other day. Lack of sleep and I took some shit out on ya. Don't want ya to fail or get discouraged so we try and get ya going in a cheap, reliable, almost foolproof fashion.
Jars, brown rice, vermiculite, and a syringe from a reliable vendor. Little patience and you'll have too much fruit.
